Hello everyone! Just joined.....hoping to find more info and things I can do to the 4.6 in my '04 Explorer. I'm getting kinda frustrated finding out that alot of the Mustang performance parts will not work on the Explorer. I work as a firefighter/paramedic in Akron, OH and on the fire-rescue crew for Nascar at Michigan Speedway. Before getting full time on the fire dept. I worked as a Ford tech for 10 years and still work part time at a local auto repair shop.
